ACM CHI+GI 1987 Issue 34 - The information lens

This video describes an intelligent system to help people share and filter information communicated by computer-based messaging systems. The system exploits concepts from artificial intelligence such as frames; production rules; and inheritance networks; but avoids the unsolved problems of natural language understanding by providing user with a rich set of semi-structured message templates. The Information Lens system uses much more detailed representations of messages contents and receivers' interests to provide more sophisticated filtering possibilities.
